This paper presents a 950-MHz wireless power transmission system and a high-sensitivity rectiﬁer circuit for ubiquitous sensor network tags. The wireless power transmission offers a battery-life-free sensor tag by recharging the output power of a base station into a secondary battery implemented with the tag. For realizing the system, a high-sensitivity rectiﬁer with dynamic gate-drain biasing has been developed in a 0.3- m CMOS process. The measurement results show that the proposed rectiﬁer can recharge a 1.2-V secondary battery over 14-dBm input RF power at a power conversion efﬁciency of 1.2%. In the proposed wireless system, this sensitivity corresponds to 10-m distance communication at 4-W output power from a base station.
